In house designed ultra low-noise power supply, custom-made transformer

High capacity main DC filter, selected audiophile series capacitors

Inputs:

For the Ayazi S/PDIF input we settled on a low-jitter re-clocking controller from Wolfson, which offered us the best sound coupled with convenience. The USB input is full class-2; to avoid damage during playback we fortified the input with our proprietary electrostatic protection, shielding the Ayazi from electrostatic discharge.

Conversion:

Unlike many other sigma-delta implementations, the converters we selected for the Ayazi incorporate patented time-domain jitter eliminator technology. This helps to deliver music free from clock jitter common in digital audio systems.

Clock:

To further refine the Ayazi’s sonic performance we selected Crystek’s CCHD-957 HCMOS oscillator. This component sports -100dB/ Hz close-in phase and a noise floor of -169dB. It matched our circuit design perfectly. Not surprisingly, the oscillator was designed for audio to begin with.

Power supply:

It took us a long time to design, refine and tune the Ayazi power supply. As usual in such devices, it is not only a matter of providing power but, especially, of maintaining a very low noise threshold as well.
